Not sure where to post this... Just installed an XFX GT520 card on my Gigabyte GA-P35-DQ6 w/ 2GB RAM and 320GB HDD, 500W PSU XP SP3, everything updated and latest Nvidia drivers Now I'm getting lots of "Delay write failed" / "Drive controller" and "Pariry" errors on Drive D (My HDD is partitioned into C and D) in Event Viewer Especially after trying to play a game or watch videos Wondering if the below stated may have anything to do with it - My "conflicting devices" list via running MSINFO32, here's what I have (I disabled the HDMI aka HD Audio port on the XFX card - no use for it): [Conflicts/Sharing] Resource Device I/O Port 0x0000A000-0x0000AFFF Intel® G33/G31/P35/P31 Express Chipset PCI Express Root Port - 29C1 I/O Port 0x0000A000-0x0000AFFF NVIDIA GeForce GT 520 I/O Port 0x00000000-0x00000CF7 PCI bus I/O Port 0x00000000-0x00000CF7 Direct memory access controller I/O Port 0x000003C0-0x000003DF Intel® G33/G31/P35/P31 Express Chipset PCI Express Root Port - 29C1 I/O Port 0x000003C0-0x000003DF NVIDIA GeForce GT 520 Memory Address 0xD8000000-0xE7FFFFFF Intel® G33/G31/P35/P31 Express Chipset PCI Express Root Port - 29C1 Memory Address 0xD8000000-0xE7FFFFFF NVIDIA GeForce GT 520 IRQ 23 Intel® ICH9 Family USB Universal Host Controller - 2934 IRQ 23 Intel® ICH9 Family USB2 Enhanced Host Controller - 293A I/O Port 0x0000B000-0x0000BFFF Intel® ICH9 Family PCI Express Root Port 6 - 294A I/O Port 0x0000B000-0x0000BFFF Realtek PCIe GBE Family Controller Memory Address 0xF6000000-0xF8FFFFFF Intel® G33/G31/P35/P31 Express Chipset PCI Express Root Port - 29C1 Memory Address 0xF6000000-0xF8FFFFFF NVIDIA GeForce GT 520 IRQ 16 Intel® G33/G31/P35/P31 Express Chipset PCI Express Root Port - 29C1 IRQ 16 NVIDIA GeForce GT 520 IRQ 16 Intel® ICH9 Family USB Universal Host Controller - 2937 IRQ 16 Intel® ICH9 Family PCI Express Root Port 1 - 2940 IRQ 16 Intel® ICH9 Family PCI Express Root Port 5 - 2948 IRQ 17 Microsoft UAA Bus Driver for High Definition Audio IRQ 17 Intel® ICH9 Family PCI Express Root Port 6 - 294A IRQ 17 Realtek PCIe GBE Family Controller IRQ 18 Intel® ICH9 Family USB Universal Host Controller - 2939 IRQ 18 Intel® ICH9 Family USB2 Enhanced Host Controller - 293C IRQ 18 Intel® ICH9 Family USB Universal Host Controller - 2936 IRQ 19 Intel® ICH9 Family USB Universal Host Controller - 2935 IRQ 19 Intel® ICH9R/DO/DH 4 port Serial ATA Storage Controller 1 - 2920 IRQ 19 Intel® ICH9 Family 2 port Serial ATA Storage Controller 2 - 2926 Memory Address 0xA0000-0xBFFFF PCI bus Memory Address 0xA0000-0xBFFFF Intel® G33/G31/P35/P31 Express Chipset PCI Express Root Port - 29C1 Memory Address 0xA0000-0xBFFFF NVIDIA GeForce GT 520 I/O Port 0x000003B0-0x000003BB Intel® G33/G31/P35/P31 Express Chipset PCI Express Root Port - 29C1 I/O Port 0x000003B0-0x000003BB NVIDIA GeForce GT 520 I/O Port 0x00000290-0x0000029F Motherboard resources I/O Port 0x00000290-0x0000029F Motherboard resources This takes me back to Win98 days, all these conflicts! Yet going into each device's properties in Device Manager, XP states "everything is ok" So far, I've tried reinstalling all of these devices listed in the above list except the XFX and they still install right back to the same memory space / IRQ
